' REPLACEABLE'BEARING FOR BRAKE-HANGERS.

To all whom it may concern:

Be it known that we, EDWIN G. CHENO- wm'H' and WILLIAM J ToLLERToN, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Imprbvement in Replaceable Bearings for Brake-Hangers, of which the following is a full, clear, concise, and exact description- Th1s invention relates to brake mechanlsm a new and improved'bearing for the brake hangers thereof. 7 y

Brake hangers are usually sup orted either from a casting formed integra with the side frame of the truck or from a casting which is riveted or otherwise secured thereto. In practice, these castings project inwardly from the side frame a suflicient distance to bring them in line with the wheels of the truck, and are provided with a plurality? of depending flanges which are drilled to receive a suitable pin from which the brake hanger is supported. These castings are subjected to great strain and jarring each time the brakes ofthe truck are applied, due to the sharp thrusts transmitted thereto by the hangers when. the} brakes which are carried at the lower ends thereof are brought to bear against the wheels; the thrusts being upward ones when the wheels, are revolving inion'e direction and downward ones when saidwhe'els are revolving in the reverse direction. It has been found that this sudden and violent j arringl caused by a reversal of the load together the constant vibration of the hanger ue to movements of the truck, soon causes ed in the bearing holes of the depending flanges of the casting, to graduallyenlarge and elongate said bearing holes.v Furthermore, if this condition is 'not promptly remedied, the casting becomes materially weakened and should thesame be broken, as is sometimes the case, the brakebeam sup-' ported thereby is very likel to drop. onto e g- 0n the other hand, the castings is the provision of 'awbearin Specification of Letters Patent.

thereby overcoming the disadvantages and" difiiculties now encountered.

Another'object is to provide anew and improved removable and replaceable bearing adapted to fit the depending flanges of the casting and to be'supported thereby, said hearing be' g adapted to receive and support the pin to which the brake hanger is attached, independent ofvthe-worn bearings of said casting whereby further wear on said worn bearings is avoided. I

A furtherobject of the present invention described which may be quic y and easily applied to any brake hanger casting of stand ardconstruction, and one: which is simple in construction and ec'friom'ical to manufacture.

" Other objects and advantages will be apparent from the following description taken so of thetypev in connection withthe accompanying drawings wherein the the invention is i1 ustrated and also several modifications thereof.

Figure 1 is a side elevation of a truckside frame, partly broken away, illustrating the application of the improved bearing.

Fig.2 is a top plan view thereof.

Fig. 3 is a sectional view taken throu 'h the side" frame and showing the bra e hanger casting and bearing in front eleva-v tion,and

Figs. 4-13 inclusive illustrate modified forms of the invention.

4 The bea'rin herein illustrated and dee same are first hanger castings 'at the time t all placed in service thereby eliminati wear thereon, reinforcing the bearing oles pplied to used hanger castings in o der t1 i9 I wait illustrated, being integral therewith. The

casting 11 projects inwardly from the frame 10 as shown, so that the end of the same will be in line with the wheels of the truck, and preferably comprises a. plurality of depending flanges 12 drilled as at 13 to receive a transverse pin 14, which pin receives the upper end of the brake hanger 15. The head at one end of the pin and the cotter pin 16 at the other end'thereof, maintain thehanger against accidental displacement'while at the same time, however, said hanger is free to swing back and forth with the movements of the brake beam as the same is moved into and out of operative position. The descrip-" tion thus far embodies nothing more than the ordinary form of truck side frame of the type, which is provided with the brake hanger castings as integral parts thereof.

Wear on the bearin holes 13 which are provided in the depen in flanges 12 of the casting may be eliminate or reduced a minimum by means of the bearing 18 which forms the subject matterof the present invention, win the event said bearing holes have already becomeworn saidbearing 18 ma be used to quickly repair and reinforce sai casting thereby -preventingfurther wear. This bearing 18 in the form of the invention shownin' Fi '1," 21and 3 is of.

Should there opening 17 in the top plate 11 of the brake hanger casting as originally constructed, such an opening may be readily cuttherein when it'is desired to position the bearing-18 thereon. a v

. ln Figs'. 1-8 inclusive, and in Fi'g. .1'3, brake hanger castin of the typewhich are adapted to be rivete or otherwise secured to the side frame of the truck areillustrated. In thisform of castin the flanges 12 also extend outwardly from the side of the frame and terminate in line with the wheels of the truck, substantially as shown, there being, however, no top plate in. this form of casting such as shown in the forms illus-- trated' in Figs 1-33 Accordingly it is not necessary to out or otherwise alter castings of this type in order that the bearing 18 Jmay, be applied thereto. -In.Fig.. 4 of th drawin'gs,the bearing is shown as-comprising 'a plurality of U-shaped members, one

for eac of the depending fianges'j 12 of the e no casting. I These membersa're adapted to fit down over the sides .of said fiangesand are also. provided with suitablebearing holes '19 which are-adapltedto alinefsubstantially I with the bearing oles131otthe, depiendin flanges.

The member22 in Fig. 9 is provided with suitable lugs24 which are adapted to lower edges of the depen ing fiangsss 12 after u tantially as shown. In this manner the upward.

and upwardly againstthe hill;

thrusts transmitted to the bearin through the loan er 15, when the brakes o the truck are app ied, are resisted.

In Fig. 8 .the invention is in the form of a bearingprovided with a suitable head or cap 21 which is adapted to restjdown upon the upperv edges of thedepending flanges 12, said head or cap 21 having riveted or otherwise securely attached .thereto a 10 U-shaped member 25 which depends from said head or cap 21 downwardly between the flanges 12. In this manner, it will be noted that a two-point bearing suspension is provided for the'pin 14: between the de- 15 pending flanges 12. The outer legs ofthe bearing are also dispensed with in-this form of the invention.

' In Figs. 10 and .12, the bearing 18 is in the same form as the bearing illustrated in .20 Figs. 1-3 inclusive with the exception that I, 'in Fig. 10 the lower ends of the lugs of the bearing are not'Iben't inwardly against' the lower edges-0f the depending flanges 12, these Figs. 10 .and 12 being included in order to illustrate a .slightly diflerent method of. attaching the hanger 15., the upper ends of said hanger beingofi'set'inwardly' rather than outwardly and attached'tothepin 14:

between. the depending flanges 12. instead of on the outside of said flanges.

In Fig. 11, the bearing IS is bent to forma suitable head 21 and 'legs which depend therefrom between thedepending flanges 12,

the lower ends of said. legs being bent outwardly and upwardly against the lower edges of said depending flanges so as to resist the upward thrusts of the hanger 15, as previouslyYdescribed. It will be noted that in Figs. 7,, 8, 9 and" 11, there is no 40 necessity foralteri'n'g the hanger 15 in view of the fact that the removable bearing 18 is provided with a bearing orlbearing sur-I faces which are ositioned-between' the dependin flanges 2, whereas in:Figs. 6 and 13 no 0 ange in the hanger isnece'ss'ary by reason ofthe faet'th'at the up er ends thereof fit betweenthelegsof the earing 18 and the sides of thexflanges 12.; a V I While the bearing herein illustrated and described is designed primarilyior usein connection with railway I truck brake I han er castings, it mayfialsofibe usedizipconnechdn' w1th spring hangers spring plank hangers bolster hangers, ete: In other 'words, said 7 bearing is of more ori less' jgeneralapplica- .tion and'it is'n'ot', therefore, desired to llmlt.
